TAGU - Tiefbau GmbH Unterweser was contracted by Van Oord Offshore Wind Projects B.V. to execute engineering and marine works for the Gemini Offshore Wind Park’s shallow-water export cable section in the Netherlands. The scope covered both an engineering contract and a charter contract to support the transport and installation campaign for the nearshore/tidal-flat portion of the export cable system. TAGU’s deliverables included engineering for the contracted works and preparation of method statements and procedures, HSE and quality documentation, and a range of technical calculations and documentation packages such as mooring calculations (cable loading and cable lay), cable calculations (loading, spooling and lay), and vessel/sea-fastening and stability calculations. The work also included producing towing documents, certificates, drawings, and equipment specifications required to execute the marine operations. For construction execution, TAGU handled loading of four approximately 8,000 m subsea cable sections at Eemshaven, transportation to the installation locations on the tidal flats, free-lay placement onto the seabed across water depths of about 1.2 m to 10 m, and spooling/hand-over of shorter cable lengths to third parties. The shallow-water export cable section comprised two parallel-laid subsea export cables, each approximately 15.5 km long. The engineering and construction phase ran from October 2014 to June 2015.
